SOLVED! 318 2500-3000 rpm idling issue. Don't think its a regular vacuum leak. Swapped 2 intakes, 2 carbs ,and 6 different gaskets still no luck.

I'm no carb expert but I think that's what the idle air bleeds are for.
Okay so I should try dropping the idle air bleeds down a size or two? There are eight, four are for under throttle and four are for idle is that correct?
